'To all whom z'zfmay concern Be it known that 1, Minnie!) W. Boron,

a subject of the King of England, residin in the town of Kearney, in thecounty or Hudson and State of New Jersey, have mvented certain new anduseful Improvements in Locking Devices for l-lutomobiles, of-

which the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it pertains to make,construct, and use the same, reference being had to the accompanyingdrawings; and to numerals oi refereiics marked thereon, forming a partof this specification.

My invention relates to a locking device, especially designed forlocking the controlling lever of any style of automobile from motion, soasto prevent the automobile from being operated 'by an unauthorizedperson, as Well as to,prevent the theft of the machine.

The object of this invention is the production of a locking device whichshall be simple in construction, durable in use, comparativelyinexpensive in cost, consisting preferably of a base plate adapted to besecured to the floor of a car adjacent tothe lever, and

-mounting upon said base plate a standard which can be adjusted towardor away from said lever, said standard supporting a pivoted locking arm,which is provided with means for interlocking engagement with saidlever.

With this end in. view, my invention consists in certain novelties ofconstruction and arrangement of parts, as hereinafter set forth andpointed out in the claims.

While thepreferred form of my invention is illustrated in theaccompanying drawings, yet it is to be understood that minor detailchanges may be made without departing from the scope there-oi.

In the accompanying'drawings, Figure 1 represents a side elevation,showing the application of the invention for holding a con-.

trol lever locked against movement. Fig. 2 represents a plan viewthereof. Fig. 3 represents an enlarged, fragmentary side elevation ofthe free end of the locking arm, just before the recess in the lockingarm engages with the stud on the hack oi"? the operating lever, andbefore the latch belt of the lock on the locking arm engages with thelatch bolt receiving element on the operating lever. Fig. 4 represents asimilar view, show-- ing the parts in locked position; and Fig. 5

represents; an end view, partly in section, taken on lines w ae of Fig.2, and looking in the direction indicated by the arrow.

Similar numerals oii reference refer to like which the standard 3 isadjustably secured to said base plate. The base plate may be secured tothe bottom of the car in any convenient or desired manner. The upper endof the standard 8 is slotted and provided with alined apertures, bymeans of which one end of the locking arm 4 is pivotally secured theretoby means of the headed stud o, The lower end of the standard 3 is pr0-vided with a suitable base 14, said base bemg provided with suitableapertures to re- '-ceive the threaded portions of the bolts 2,

and by means of which and suitable nuts, the standard may be adjustablysecured to thebase plate 1. 4 is. provided with a recess 6, designed tohave holding engagement with a stud 7 secured to one side of theoperating lever 8 in any convenient and desired manner, and by means of'whi'ch the arm. 4 has holding engagement (with the operating lever 8.Secured to o-h side of the arm 4 at its free end,

-is. adock case '3, preferably of the pin-cylinder type, and secured tothe operating lever 8 is a latch bolt receiving element 10, adapted toreceive the latch bolt 11 of said lock, and by means of which the arm 4:is posi tively locked to the operating lever 8, as clearly indicated inthe different views of the drawings.

Although I have shown in the drawings thelatch bolt receiving element 10secured to the face of the operating lever 8, it is to be understoodthat for convenience sake, the same may be secured to the opposite sideof the lever to which the stud 7 is secured.

By means'of the slots formed in the base plate 1, the standard may beadjusted so as to dispose the same at diii'erent distances from theoperating lever 8 for effective ongagement of the holding and lockingmeans, if for obvious reasons the distance from the end of the standard3 and the operating lever 8 should vary. When the device is not in use,the locking arm 4 may be swung u. ward into engagement with asmhb e Thefree end of the arm spring-clasping member '12 secured to the .car atany convenient point and with which it has frictional engagement, asclearly indi rated in the dotted lines in Fig. 1 of the drawiPgS.

In the operation oi this mechanism, the operating lever 8 isilocked byswii'iging the arm 4. from the position shown in dotted lines into theposition shown in full lines in Fig. l of the drawings, which operationsimultaneously causes the recess 6 of the locking, arm to engage withthe stud 7 on the lever 8, and permits the latch bolt 11 of the lock 9to autoi'natically enter into looking engagement with the latch boltreceiving element 10. When it is desired to use the machine which islocked b this meo ha nism, the operator by means of a key not shown),releases the latch bolt 11 from locking engagement with the latch boltreceiving element 10, and the arm -lis then free to be swung upward intoengagement with said spr'ngelasping member 1.2, which maintains said arm4 out of operating position until again needed.

It will be understood that the construction and arrangement andcombination of the parts above shown, are given only to illustrate thepractical embodiment of my in vention; and experience has demonstratedthat the same is a highly cilieient device, but it, is obvious thatminor Variations thereof, not involving the exercise of inrei'ition, maybe made by any skilled meehai'iic, and such departures from what isherein described and claimed, not involving invention, I consider withinthe scope and terms of my claims.

Having thus described my invention, what I desire to claim is:

1. In a device for securing an operating lever, a base plate providedwith slots secured to the floor of a car, a standard designed to beadjust-ably secured in said base plate by means of said slots toward andaway from the operating lever, an arm pivotally secured to saidstandard, the free outer end of said arm being provided with a recess,stud secured on said operating lever adapted to be engaged by the recessin said movable arm, piiroylinder means secured on said movable arm, akeeper on said operating lever in close proximity to said stud, saidpin-ovlinder means adapted to engage with said keeper, whereby when saidmeans are in. locking engagement with said keeper, said stud and recessare in further engagement, for looking and holding said operating leverin its normal position.

In a device for securing an operating lever, an adjustable standard, anarm pivoted to said standard adapted to he engaged by and disengagedfrom the operating lever, the free outer end of said arm being providedwith receiving means, holding means secured on said operating leverdesigned to engage with the said receiving means on said movable arm,pin cylinder means also secured on the free outer end of said movablearm, a keeper on said operating lever in close proximity to the means onsaid operating lever, said pin-cylinder means adapted to engage withsaid keeper, whereby when said means are in looking engagement with saidkeeper, the firstanentioned means on both the movable arm and operatinglever are also in enga' enient, for hacking and holding said oyez" tinglever in its not mal position. i V
